WILLIAM JACKSON, OF ALBANY, NEW YORK, ASSIGNOR TO HIMSELF AND HENRY G.WILKINS. OF SAME PLACE.

Letters Patent No. 102,822, dated May 10, 1870.

IMPROVEMENT IN CHURCH-ORGANS The Schedule referred to in these LettersPatent and making part of the same.

' panying drawings forming a part of this specification,

in which Figure 1 represents a perspective view of an orgar, withimprovements.

Fignre 2 is a longitudinal cross-section through airchamber, andsupplementary air-chamber attached.

Figure 3 is a cross-section of the same, viewed from the front.

Figure 4 is a side view of stops, draw-rods, \vith'the composition barand theirlevers attached.

Figure 5 is an end view of the same.

Figure 6 is a longitudinal moss-section of a pipe.

Figure 7 is a view, from back, of the apparatus for operating thebellows.

- To secure a constant flow of air from the bellows into. theair-chambers, I operate the bellows by a number of levers and bars,which are worked by a crank formed on the shaft of a fly-wheel, whichfly-wheel is turned by a handle, and operates the several bellows insuch a way as will bring up some one or more of the bellows while theothers are going down.

I also attach to the draw stop-rods one extra arm each, and thesaidextra arms pass between what I call composition bars, which are fittedtogether in pairs, and are connected by T-headed levers at either end,and may be operated by pneumatic valves or the knees or feet of theoperator, who can, by them, work quickly the stops, and throw them in orout at will.

To enable others skilled in the art to make and use my invention, I willproceed to describe it in reference to the accompanying drawings andletters of reference marked thereon, the. same letters referring 'tolike parts. I

AA is any suitable frz'nne-work for an organ to be constructed.

Upon the lower platform p, figs. 1 and 7, is placed the usualair-chamber B; This air-chamber B is fed oy two or more bellows, C G,figs. 1, 2, 3, and 7, operated as follows:

A fly-wheel, W; furnished with a crank-shaft, a, supported by suitablestandards, 3 s, operates a carrying block, I). To each end of the saidcarrying-block are attached the bars 0 c, which connect with and operatethe-angle-levers (Z d, supported by the standards s s. Connected withone of the arms of the levers d (l are the connecting-bars e e, which.are attached to the lifting irons of the feeders or bellows c c. If

three feeding-bellows are to be used, I connect with the carrying-block71 a third connecting-bar, c, the lower end of which is attached to thelifting-iron of the said third bellows C, and, when the fiy-wheei \V isrevolved, the crank a carries the carrying-block b back and forth, andup and down, thereby working the feedingbellows 0-0 G alternately, onefeeder being full, one empty, and the other partially/filled.

'lo readily operate the stops P and slides r the raw-rods k k arefurnished with extra arms in on, and the said arms in operate thecomposition bars a n, which are coupled in pairs, as shown in figs. 4and 5, one. bar of each pair being placed above and one below. Attachedto the heads of the composition bars a n are the T-headed levers 0,which may be operated by pneumatic valves, or by the knees or feet ofthe operator. The heads of the composition bars may be used on eitherend with the T-levers. Pins t t are placed in the upper and lower barsof the composition bars at n, which operate the draw stop-irons k itupon any combination of the stops before agreed upon.

Having thus described my invention, 7

What I claim. and desire to secure by Letters Patent, is-

1. In combination 'with the bellows O O of a churchorgan, the fly-wheel-W, with the crank a, bars 0 c, levers (Z d, and connecting bar e c,constructed and em ranged substantially as described and for the purposespecified.

2. The extra arms in of the draw stop-irons k, in combination with thecomposition-bars n a and their pins t, and the T-headed lever o, as andfor the purpose set forth and described.
